I want the tree not to be selected, not expanded.
so when the tree is displayed, a postback is generated, as if the user clicked on the node itself to select it.

Well the state of your page will change if you run a piece of javascript code

 you're kidding right?? You're expecting the rendered HTML of a gridview to magically become an image just because you're loading that HTML into an image?
Sorry buddy, it ain't gonna happen!
|

|
|

Is there any other way to achieve this.
I mean i have to capture gridview as Image.
|
|
|
|
|
Print Screen.
That really is an awful question.

Thanks .netman.
My requirement is to convert only Gridview into Image. Not the Entire page or Screen, these are i already did it.
If you know any other way to do that, let me know.

No, there is not any built-in method for doing this. Certainly expeecting the HTML to render as an image is not going to work as stated.
About the only way I can think of doing this is to create a blank Bitmap, and draw a table using the GDI+ drawing methods. You could read the columns/rows from your gridview and replicate this on the bitmap.

Hi,
i have problem in ie6 with the onfocus event.The onblur and onfocus event execute some javascript code. The problem is , in mozzilla this work ok, in ie6 work only for some objects.
Fe: for the companyname textbox the browser didnt apply this 2 events, the select object work fine.
Can u help me in this problem?
I add this event to my object fr5om code behind:
in page load :
..
Me.companyname.Attributes.Add("onFocus", "changehint('hint1',2)")
Me.companyname.Attributes.Add("onBlur", "check_field('companyname',this.value,'hint1')")
Me.state.Attributes.Add("onfocus", "changehint('hint4',2)")
Me.state.Attributes.Add("onblur", "check_field('state',this.value,'hint4')")
My aspx page looks like this
...
<table style="text-align:left;">
<tbody>
<tr class="row">
<td ><asp:Label ID="txtcompanyname" runat="server" Text="name + form"></asp:Label>*
<br /><asp:Label ID="obs_name" runat="server" Font-Size="9px"></asp:Label></td>
<td><asp:TextBox ID="companyname" runat="server" ></asp:TextBox>
</td>
<td>
<span id="hint1" class="hintForRegistration ">
<asp:RequiredFieldValidator CssClass="hinttext" ID="reqname" Display="Dynamic" runat="server" ControlToValidate="companyname" ErrorMessage="error1"></asp:RequiredFieldValidator>
<asp:label ID="Label0" runat="server" CssClass="hinttext"></asp:label></span>
</td>
</tr>
<tr class="row">
<td><asp:Label ID="txtcompanycounty" runat="server" Text="county"></asp:Label>*</td>
<td>
<select id="state" runat="server" >
<option selected="selected" value=""></option>
<option value="Baranya">Baranya</option>
</select></td>

</span>
</td>
</tr>
The javascript code change hintbox style on onfocus or onblur event:
function changehint(elem,type,label)
{
var hint = document.getElementById(elem);
hint.style.visibility = "visible";
if (type == 1)
{hint.className='hintForRegistration red';}
else if (type == 2)
{hint.className='hintForRegistration orange';}
else if (type == 3)
{hint.className='hintForRegistration blue';
hint.innertext = 'OKSA!';}
}
function check_field(thefield,thevalue,thehint)
{
if (thefield == "companyname" || thefield == "state" || thefield =="companystreet" || thefield =="companycity")
{if (validate_anytext(thevalue)) changehint(thehint,3)
else changehint(thehint,1)
}
else if (thefield == "companymail")
{if (validate_email(thevalue)) changehint(thehint,3)
else changehint(thehint,1)
}
else if (thefield == "companypass1" || thefield == "companypass2")
{if (validate_pass(thevalue)) changehint(thehint,3)
else changehint(thehint,1)
}
else changehint(thehint,3)
}
thanks

If this is a direct copy of your code, your solution may be really simple: check casing when assigning the attributes to Me.CompanyName. You have "onFocus" in that control, but "onfocus" in the State control.
Have faith in yourself; amateurs built the Ark, professionals built the Titanic.

i try it but not work.
The freaky thing is, when i make a save page as and i start the local copy in ie6, everything works fine. I must mention the page was saved in Ie6, so the generated code is the same.
In developer toolbar the textbox doesnt have the onfocus and onblur event.
thanks

Good for you. Is there a specific problem? Have you perhaps looked at the section of the toolbox that contains the validator controls...?
|
|
|

What a required field validator?
Be more specifc?

I'm trying to make a data bound column invisible after data binding, because it won't exist before data binding. However, the DataGrid.Columns collection indicates a count of 0, making it seem as if the automatically generated columns don't belong to the collection.
How can I make a column that is automatically generated during binding invisible?
|
|
|
|
|
on the basis of your condition
if(Condition)
gv.columns[no].visible=true;
else
gv.columns[no].visible=false;
|
|
|
|
|
As I stated in my question, the columns collection is empty.
|
|
|
|
|
Have you tried doing in the event handler for DataBound? I presume that the auto-generated columns are created when the control data binds.
|
|
|
|
|
I'm currently doing it in the ItemCreate event, with success, thanks.
It was even after the DataBind call that the Columns collection was empty. I wonder if the call is asynchronous?
